As you can see the individual ticket costs for your trip are slightly lower than that of a 7 day pass. Whether you go for the 7 day pass or not really depends on how flexible you'd like to be in the 7 day period. As the prices are relatively similar, I think I'd go for the JR Pass option, however you should weight it's convenience and speed against the possible savings by travelling by bus before you make your decision.

Your prompt and detail reply is very helpful for me. I have decided to go for the JR Pass, as it give me a whole lot of flexibility and extra time to travel anywhere I like with less hassle, Thank you very much for your great assistance.

As a holder of JR West Kansai Wide Rail Pass, I want to travel from Osaka/Kyoto to :
A. Amanohashidate
B. Kinosaki Onsen

My Questions:
1. Are both areas covered by the Pass?
2. How much is the extra fare and charges needed to go to Amanohashidate?
3. Can I travel directly from A to B using the Pass?
4. How long will it take from A to B?
5. Is it possible to go to both places within a day trip?

I think that the Kansai Wide will cover the locations you mention but as this pass is relatively new I'm not 100% sure of the precise details. The WIDE area pass does cover Kinosaki Onsen and I think not Aminohashidate (it's not very clear from the JR-West documentation). I recommend you contact JR-West directly using this contact form to find our more information. If you could report back here it would be most appreciated!

Thank you very much for your very helpful information regarding the use of JR Pass to travel within the remote areas near Japan Sea.

I was able to travel comfortably and easily between the two places, paying extra small fee of 680 Yen each way to cover for the private KTR (Kinki Tango Railway) train between Fukuchiyama and Miyazu City. For traveling to Kinosaki Onsen from Fukuchiyama via Toyooka, on the other hand, is fully covered by the JR Pass. I had a great time indeed!
